Server virtualization enables dramatic increases in efficiency in the
datacenter. The ability for multiple virtual servers to share the same
underlying physical resources sets the stage for dramatic reductions in
physical server counts and corresponding capital and operating costs.
But how far should this sharing be pushed? At what point does the
sharing of resources become dangerous?

VKernel's new white paper, “Best Practices for Oversubscription of CPU,
Memory and Storage in vSphere Virtual Environments,” discusses methods
for effectively managing oversubscription of CPU, memory and storage
resources. The paper addresses the pros and cons of oversubscription
and, based on a number of real world discussions, proposes ideas about
the point at which oversubscription becomes dangerous. This paper also
explains how VKernel's free tool, vOPS
Server Explorer, provides at-a-glance information about
oversubscription as well as insight into the overall performance and
capacity of your virtual environment.
